VPIM Networking

Cisco Unity supports the Voice Profile for Internet Mail (VPIM) protocol, which is an industry standard

that allows different voice messaging systems to exchange voice, fax, and text messages over the Internet

or any TCP/IP network. VPIM is based on the Simple Mail Transfer Protocol (SMTP) and the

Multi-Purpose Internet Mail Extension (MIME) protocol.

For information about the VPIM-compliant voice messaging systems that Cisco Unity supports, see

Supported Hardware and Software, and Support Policies for Cisco Unity, at

http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html. Note

that VPIM Networking can be used for messaging between Cisco Unity servers that are in different

directories, including messaging between Cisco Unity with Microsoft Exchange and Cisco Unity with

IBM Lotus Domino systems.

VPIM Networking is a licensed feature. If your organization has multiple Cisco Unity servers networked

together using Cisco Unity Digital Networking (and, therefore, accessing subscriber data in the same

directory), only one server in the Digital Network needs to be licensed and configured for VPIM

Networking. The Cisco Unity server configured for VPIM Networking is referred to as the bridgehead

server. For more information on obtaining licenses for Cisco Unity features, see the applicable Licensing

for Cisco Unity white paper, at

http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_white_papers_list.html.

To use VPIM Networking, you must choose the applicable options when you run the Cisco Unity

Permissions wizard. For detailed information, see Permissions wizard Help, which is available in Tools

Depot on the Cisco Unity server.
